REQUIRED SKILL LEVEL: Basic Skill Required REQUIRED TOOLING: Basic Hand Tools Required ESTIMATED TIME OF INSTALLATION: up to 60 Minutes This Bosch oxygen sensor installs universal. You need to cut the harness of existing sensor and establish connections on wires across vehicle harness and new sensor wires, with shielded bullet connectors or soldering. Setup can be conducted in less than 60 minutes by a mechanical minded installer being slightly inclined with electronics.

Disconnect old oxygen sensor connector from vehicle harness using extra care not to damage connector, as it must be re-used.

Remove old sensor from vehicle using an O2 sensor socket or 22mm wrench. Place the old and new oxygen sensors side by side on a flat surface, preparing to make an accurate cut of the lead wires. Cut the lead wire(s) to a length that when the plug end is spliced to the new universal sensor, the overall length will be the same or slightly longer than the old sensor.

Stagger-cut wire lead(s) stripping off approx. 1/4” of insulation from the end of each wire. For steps #4 and #5 please refer to the Manufacture Wire Colors image to determine proper wire matching of universal sensor lead(s) to connector lead(s) for each specific application (heater wires are not polarity dependant).A) On universal sensors where heat-shrink tube(s) are already installed: insert just striped portion of wire(s) into crimp terminals of new sensor and crimp terminals. B) On universal sensors where heat-shrink tube(s) are not installed: insert just striped portion of wire(s) into crimp type "butt" connectors (approx. 1/4”) and crimp.

After all connections have been made, slip the heat shrink tube over the crimped connections and heat the tube with an appropriate heat source until the connection is completely sealed, taking care not to over-heat or burn tubing see image.

Remove protector cap just prior to installation A) Flanged applications-(where flange is not already installed on sensor) Install flange to exhaust manifold first, then mount sensor in flange (a copper gasket is bonded to the flange no additional gasket is required) B) Flanged applications- (where flange is already installed on sensor) it is important to use the supplied gasket before installing sensor).

Note

Install all sensors with new gasket supplied torque to proper specs as follows: M18 sensors - install finger tight then 1/2 -3/4 turn with wrench, then secure with 22m socket using 35Nm torque

Connect and route lead wire as originally installed.

Working Theory

An automotive air fuel sensor – had been invented by Bosch - is a small sensor inserted into the exhaust system of a gasoline engine to measure the concentration of oxygen remaining in the exhaust gas to allow an Electronic Engine Management to control the efficacy of the combustion process in the engine. In most modern vehicles, like Ford Transit Connect these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to your Ford Transit Connect's engine management, which adjusts the mixture to deliver the engine the best possible fuel efficiency and lowest possible exhaust emissions.

Bosch patented ceramic technology affords best-in-class performance. The ceramic element is a critical part of the exhaust o2 sensor. Bosch's patented materials and processes ensure unsurpassed quality and engine performance. Also it sounds reassuringly, major vehicle manufacturers place their trust in Bosch lambda sensors. Why replace? Failure of these lambda sensors, either through normal aging, the use of leaded fuels, or due to fuel contamination with eg. silicones or silicates, can lead to damage of your Ford Transit Connect's cat converter and expensive repairs.

Compatibility

Our Bosch lambda probe is available to all vehicles fitted with 1 up to 4-wire zirconia o2 sensors, torqued in M18 x 1.5mm threaded nut. This exhaust air fuel sensor will fit your Ford Transit Connect if it is fitted with 1 up to 4-wire narrowband zirconia o2 sensor, front or post. Not quite sure this lambda sensor fits your Ford Transit Connect? Feel free to contact our Tech Support. Our trained Magnum product specialists are looking forward to respond to your inquiry. Heavy exhaust alterations like decat test pipes, catless exhaust systems or headers trip engine management warning light. In this instance the replacement of the exhaust oxygen sensor will not cease MIL issues. If so, you need to wire up oxygen sensor simulator to the post oxygen sensor(s)' harness in order to get rid of PCM limp mode causes the engine run inefficiently spoiling both power output and economy.

o2 sensors are recommended to be replaced after each 50.000 miles - 80.000 km.

Good to know that Bosch invented the air fuel sensor and it is first choice for exhaust air fuel sensors throughout the world. An annual production of around 38 million exhaust o2 sensors impressively demonstrates the high quality and skill delivered by Bosch. It therefore comes as no surprise that most Customers driving Ford Transit Connect preferably choose a Bosch lambda sensor when replacement interval passed.

All Bosch exhaust air fuel sensors come with special features. Double laser-welded stainless steel body protects the sensor against contamination. Pre-coated threads with anti-seize compound guarantees easy install and removal at any time. If original exhaust o2 sensors are worn on your Ford Transit Connect or give slow signal, you can save up to 10% a year in gasoline costs! Check your lambda sensor frequently on your Ford Transit Connect and replace them with every second tune-up to improve vehicle horses and reduce harmful exhaust emissions.

Oxygen sensors are used to reduce vehicle emissions, by ensuring that engines burn their fuel efficiently and cleanly. Robert Bosch GmbH introduced the first automotive lambda probe in 1976. The sensors were introduced in the US from about 1980, and were required on all models of cars in many countries in Europe in 1993. By measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can use look-up tables to determine the amount of fuel required to burn at the stoichiometric ratio (14.7:1 air:fuel by mass for gasoline) to ensure complete combustion. When an internal combustion engine is under high load (such as when using wide-open throttle) the oxygen sensor no longer operates, and the engine automatically enriches the mixture to both increase power and protect the engine.

Internal Design

The sensor element is a ceramic cylinder plated inside and out with porous platinum electrodes; the whole assembly is protected by a metal gauze. It operates by measuring the difference in oxygen between the exhaust gas and the external air, and generates a voltage or changes its resistance depending on the difference between the two. The sensors only work effectively when heated to approximately 300°C, so most lambda probes have heating elements encased in the ceramic to bring the ceramic tip up to temperature quickly when the exhaust is cold. The probe typically has four wires attached to it: two for the lambda output, and two for the heater power. h5Operation of the Zirconia O2 Sensor/h5 The zirconium dioxide, or zirconia, lambda sensor is based on a solid-state electrochemical fuel cell called the Nernst cell. Its two electrodes provide an output voltage corresponding to the quantity of oxygen in the exhaust relative to that in the atmosphere. An output voltage of 0.2 V (200 mV) DC represents a lean mixture. That is one where the amount of oxygen entering the cylinder is sufficient to fully oxidize the carbon monoxide (CO), produced in burning the air and fuel, into carbon dioxide (CO2). A reading of 0.8 V (800 mV) DC represents a rich mixture, one which is high in unburned fuel and low in remaining oxygen. The ideal point is 0.45 V (450 mV) DC; this is where the quantities of air and fuel are in the optimum ratio, called the stoichiometric point, and the exhaust output will mainly consist of fully oxidized CO2. The voltage produced by the sensor is so nonlinear with respect to oxygen concentration that it is impractical for the electronic control unit (ECU) to measure intermediate values - it merely registers "lean" or "rich", and adjusts the fuel/air mixture to keep the output of the sensor alternating equally between these two values. This type of sensor is called 'narrow band', referring to the narrow range of fuel/air ratios to which the sensor responds. The main disadvantage of narrow band sensors is their slow response: the control unit determines the exhaust gas composition by averaging the high and low swings in the sensor's output, and this process creates an inevitable delay Not quite sure this oxygen sensor fits your vehicle?

every thing went together perfect

every thing went together perfect, except for stripped nut the previous owner didnt change the o2 sensor and it was rusted, otherwise would have taken less than an hour to change out the senor on my volvo, highly recommend

satisfied with this product

I am satisfied with this product. A heads up for those people may be a litle ignorant, you need to cut the factory pigtail so dont expect direct replacement, read web site info, as regrattably i did NOT.
